This would be interesting to create, but would take a bit of work. There's so many methods for doing this as well, that it would be hard to choose one. Nothing connected to the forum database itself though, as we don't want any security flaws in the kind of user access we allow. It could be a p2p application which has connections from every application downloaded by a member. But then we would have to have a database that gets updated by user input for the application appart from our actual forum database. The database could serve like an updated information gallery on threads that haven't been solved yet, and those that have been solved. The application would show your queries to the database, and as well as others queries to it to give everyone a display of all of the entries for things that have been solved, and others that haven't been solved.

Maybe even a sorting function for solved, and unsolved entries?

To include it with the forum, there would have to be a textbox, where you'd have to manually input a link to your thread on the mybb forum, so that people could click your entry and be directed to the link through a process that opens up your web browser.
